First of all you should know that "USDT Dominance" is always the inverse of BTC USDT.
USDT Dominance refers to the percentage of Tether (USDT) in the total crypto market cap. It shows how much capital flows into or out of stablecoins like USDT compared to other cryptocurrencies. When USDT dominance increases, it suggests investors are moving into stablecoins, potentially indicating fear or uncertainty in the market.
BTC correlation with USDT dominance is typically inverse. When USDT dominance increases, it often suggests that traders are moving out of Bitcoin (BTC) and other cryptos into USDT, leading to a potential drop in BTC price. Conversely, when USDT dominance decreases, it may indicate that traders are moving funds from USDT into BTC, potentially driving BTC's price up.
Due to the news of the war in the Middle East, selling pressure has been very strong in the crypto market for several days.
As you can see on the chart USDT.D is moving in the ascending channel for approximately 205 days. After USDT.D breaks below from the ascending channel we could see a very bullish move in the Bitcoin price and as you know Altcoins follow it.
Everything is on the chart.
